About six months ago I found a first gen MacPro for $180. I have 32GB of RAM in mine. I lucked out and got the ram in trade for some work.

I don't use it much for 2 reasons. One it pulls a lot of power. According to my PDU it pulls about 220 Watts at idle.

The other thing is that the CPUs don't have EPT support. So it causes problems with running nested hypervisors, which pretty much rules it out for my lab use.

I'm not sure I'm going to keep it. I don't find it very useful.
